This driver was declared obsolete over 2 years ago, the alternative
console driver for legacy iSeries (hvc_iseries) was made the default
over 1 year ago and this driver has been build broken for over 3
months, so remove it.Signed-off-by: Stephen Rothwell

I also added a small Kconfig change that allows the user to specify the
virtio console in menuconfig.(Fixes to export symbols from Stephen Rothwell )
(Fixes for CONFIG_VIRTIO_CONSOLE=y vs CONFIG_VIRTIO=m from Christian himself)Signed-off-by: Rusty Russell
Cc: Stephen Rothwell -
This patch tries to change hvc_console to not use request_irq/free_irq if
the backend does not use irqs. This allows virtio_console to use hvc_console
without having a linker reference to request_irq/free_irq.In addition, together with patch 2/3 it improves the performance for virtio
console input. (an earlier version of this patch was tested by Yajin on lguest)The irq specific code is moved to hvc_irq.c and selected by the drivers that
use irqs (System p, System i, XEN).I replaced "int irq" with the opaque "int data". The request_irq and
free_irq calls are replaced with notifier_add and notifier_del. I have also
changed the code a bit to call the notifier_add and notifier_del inside the
spinlock area as the callbacks are found via hp->ops.Changes since last version:
o remove ifdef
o reintroduce "irq_requested" as "notified"
o cleanups, sparse..I did not move the timer based polling into a separate polling scheme. I
played with several variants, but it seems we need to sleep/schedule in
a thread even for irq based consoles, as there are throttleing and buffer
size constraints.I also kept hvc_struct defined in hvc_console.h so that hvc_irq.c can access
the irq_requested element.Feedback is appreciated. virtio_console is currently the only available console
for kvm on s390. I plan to push this change as soon as all affected parties
agree on it. I would love to get test results from System p, Xen etc.Signed-off-by: Christian Borntraeger

More Kconfig tweaks related to the legacy PC RTC code:
- Describe the legacy PC RTC driver as such ... it's never quite
been clear that this driver is for PC RTCs, and now it's fair
to call this the "legacy" driver.- Force it to understand about HPET stealing its IRQs ... kernel
code does this always when HPET is in use, there should be no
option for users to goof up the config.This seems to fix kernel bugzilla #10729.

Make /dev/kmem a config option; /dev/kmem is VERY rarely used, and when
used, it's generally for no good (rootkits tend to be the most common
users). With this config option, users have the choice to disable
/dev/kmem, saving some size as well.A patch to disable /dev/kmem has been in the Fedora and RHEL kernels for
4+ years now without any known problems or legit users of /dev/kmem.[akpm@linux-foundation.org: make CONFIG_DEVKMEM default to y]

Kconfig tweaks to help reduce RTC configuration bugs, by avoiding
legacy RTC drivers when the generic RTC framework is enabled:- If rtc-cmos is selected, disable the legacy rtc driver;
- When using generic RTC on x86, enable rtc-cmos by default;
- In the old "chardev RTC" section of Kconfig, add a comment
warning people off these (seven) legacy RTC drivers when
the generic framework is in use.People can still use the legacy drivers if they want (or need) to.
This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver.
Ideally it would be a full list of platforms where it works, not a partial
list of ones where it won't. Or better yet, it would depend on a
"HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a
Kconfig style guideline lurking there.Signed-off-by: David Brownell

After analyzing the elements that save_flags/cli/sti/restore_flags were
protecting, convert their usages to a global spinlock (the easiest and
most obvious next-step). There were some usages of flags being
intentionally cached, because the code already knew the state of
interrupts. These have been taken into account.This allows us to remove CONFIG_BROKEN_ON_SMP. Completely untested.

This includes code for new fifo-based xps_hwicap in addition to the
older opb_hwicap, which has a significantly different interface. The
common code between the two drivers is largely shared.Significant differences exists between this driver and what is
supported in the EDK drivers. In particular, most of the
architecture-specific code for reconfiguring individual FPGA resources
has been removed. This functionality is likely better provided in a
user-space support library. In addition, read and write access is
supported. In addition, although the xps_hwicap cores support
interrupt-driver mode, this driver only supports polled operation, in
order to make the code simpler, and since the interrupt processing
overhead is likely to slow down the throughput under Linux.Signed-off-by: Stephen Neuendorffer

This is an hvc-based virtio console driver. It's suboptimal becuase
hvc expects to have raw access to interrupts and virtio doesn't assume
that, so it currently polls.There are two solutions: expose hvc's "kick" interface, or wean off hvc.
